I updated my phone to version 32.2.A.0.253 last month. During the month, I have to use the vpn on the mobile data for some bussiness purpose. However, the vpn always can use for a few minute and then the vpn is down but service alive and chrome always give me a dns problem. I try that wifi is ok and other mobile phone(not sony) is ok and pc is ok.
I think it maybe a bug because i find that some other people always have the problem the he use the Sony X Performance.
